PRODUCT INTRODUCTION
                                                                                                                                                              
 

The function of trailer leaf spring

1. Load Support
Primary Function: Supports the weight of the trailer and its cargo, distributing the load evenly across the axle(s).
Heavy-Duty Capacity: Designed to handle varying loads, from light-duty utility trailers to heavy commercial trailers.

2. Suspension & Shock Absorption
Flexibility: The stacked steel leaves flex to absorb road shocks, bumps, and vibrations, improving ride stability.
Durability: Made of high-strength steel to withstand repeated stress without breaking.

 

3. Axle Positioning & Stability
Keeps Axles Aligned: Helps maintain proper axle spacing and prevents lateral (side-to-side) movement.
Reduces Sway: Enhances trailer stability, especially when cornering or on uneven terrain.

4. Enhanced Traction
By maintaining consistent tire contact with the road, leaf springs help improve traction, especially when hauling heavy loads.

5. Simple & Reliable Design
Low Maintenance: Unlike air suspensions, leaf springs have fewer moving parts, reducing the need for frequent repairs.
Cost-Effective: More affordable than complex suspension systems while still providing reliable performance.

ACCURATELY MEASURE YOUR TRAILER AXLE

                                                                                                                                                              

Accurately measuring your trailer springs and choosing the correct replacements is important for the function of your trailer and will make the job of replacing them much easier. Using replacement trailer springs with the correct length will keep the axle in the same position, eliminating the need to move guards or suspension components like spring hangers. Matching your weight capacity, arch, and leaf count will keep the ride height of the trailer the same and keep the ride characteristics the same. 

Determining when to replace trailer springs
Noticing the following could warrant such actions even if a spring isn't technically broken:
-Suspension dipping on one side
-Obvious signs of corrosion or cracking
-Creaking or squeaking
-Tire wear, unusually high
-Consistently scraping the bottom when crossing bumps
Should always be per axle, replacing leaf springs helps maintain balance and consistent performance.

Step 1: DETERMINE THE TYPE OF TRAILER SPRING 

 

Step 2: MEASURE THE WIDTH OF THE TRAILER SPRING

Step 3: MEASURE THE LENGTH OF THE TRAILER LEAF SPRING
To measure the free length, refer to letter "C" above. It is important that your trailer is unloaded when measuring the length. When determining length (C), measure from the center of one spring eye to the center of the other spring eye for double eye trailer springs. 

Step 4: DETERMINE THE CAPACITY OF THE SPRINGS

Step 5: MEASURE FREE OPEN AND ARC OF THE TRAILER SPRING
Measure the free open (H) and the arc (A) and (B) of the trailer spring. These measurements are more for reference and will change with the age and fatigue of your spring.
